ARC Screen

The arc screen is a Print cleaned mechanical bar screen specifically developed for small plats. The screen has a spring loaded rake that rides over compacted debris, in lieu of jamming. This screen is for channels 12-25" wide to a maximum of 36" deep. The screen removes debris from the incoming fluid by means of a bar rack. The bar rack is formed into an arc and mounted on a self-standing support frame. The unit is driven by a cost effective shaft mounted gear motor, controlled by an electronic overload device. The arc screen has no underwater parts subject to maintenance. This screen is very reliable and cost effective for low flow conditions and small plants.

The screenings are hold on curved bar screens causing a clogging and as the water flow reaches to set level sending a signal to start the raking mechanism. The raking arm which is connected to the chassis is lowered in the channel and rake teeth enter between the very low point of the bar screen. During upwards movement the screenings are dragged and collected by the rake. Finally at the discharge point the debits are removed by cleaning to a container or a transporter for further processing.
